Jewelry Photo Cropping Editing and Color Correction

We are looking for a photoshop expert to: Crop the jewelry, meaning to knock out the background; Minor editing, meaning to touch up the photo and remove any black spots or blemishes, and finally do some color correcting. We will give examples of how and what kind of color the jewelry should be. We would like to get a quote for 50 images. If the work is done right, we will continue to provide a larger supply of images to be edited. We will provide a sample during PM and I expect a return sample of your work. If this is satisfactory, we will proceed.
